They generate oxygen in limited quantity only sufficient for people to survive. The oxygen needed to burn fuel is 100s of time more than that. It is one thing to get limited quantity of oxygen for breathing and another thing to use that for burning fuel

The point here is that if the electricity generated from fuel cell used to generate Hydrogen, then what is the point of the electricity at all? If we are splitting water with electricity, 2e might as well use the same electricity to power the submarine. Why waste electricity like this? So...

How can you generate Hydrogen on board? Are you talking of methanol to hydrogen synthesis?

I am only speaking of DRDO fuel cells. DRDO fuel cell is scalable. It simply requires multiple fuel cells placed in series and parallel to increase capacity. If you are thinking that entire submarine will be powered by 1 fuel cell, then you are wrong. Just like Tesla battery pack has many...

Actually, the AIP technology is one size fits all. It is just that the design of the submarine has to be changed. The design doesn't involve any new technology but simply change in the shape and mechanics of the submarine to accommodate the weight and space balance.

I understand what you are saying. I am only saying that submerged submarine doesn't need non magnetic property. Submergence will by itself reduce it. Secondly, if the submarine is snorkeling, then its its metal and heat will simply give away its location to aerial ASW assets via radar or IR...

South Korean submarine uses Germany engine. So, no full ToT. Exporting it is like China exporting Jf17 to Pakistan with Russian engine. Magnetic anomaly is for surfaced or snorkeling Submarine. It is not for submerged ones. Submerged submarine can't be found by magnetic property but are found...

Germany submarine is no longer as high end as Russian or French new models. Geemany technology has reached its limits. Moreover, Germany is reluctant to give full technology transfer. Only partial technology will be offered. Russian electronics are not behind USA in defence. USA also uses older...

USSR did lose some advantage over USA when USA semiconductor grew in 1970s while USSR semiconductor technology didn't grow as fast. But even then, the difference was not too much. Indian Kilo Class submarine works very well and have no operational deficiency compared to German shishumar ones.

This is called as lost decade by Russians where the Technology stagnated due yo disintegration of USSR and scattering of the technology manufacturing bases across the states. But, Russia has started to develop their Technology since 2000 and has succeeded in doing so. As of now it has good...

Russia wants to build P75I submarines, says India needs better vessels than Scorpene Russia is eyeing building the next generation of conventional submarines for the Indian Navy, a mega contract worth about Rs 80,000 crore, with Moscow pitching in strongly for a joint design and production...

We don't want all nuclear submarine. Nuclear submarine is difficult to start after repairs. Nuclear submarine has higher noise. Considering that Indian zone is mainly in IOR, which holds the biggest oil reserves, it makes no sense to have nuclear submarine in large numbers. Nuclear submarine may...

HUGE BLOW for all those who said the third scorpene will be named as INS VELA

Good news - India to get indigenous AIP for all 6 scorpene submarines http://www.thehindu.com/news/national/scorpene-submarines-to-get-indian-aip-modules/article19700162.ece

Yes, I know that. I got confused. Lets move any further conversations regarding yhin in chit chat to avoid derailing thread.

Velam or something similar is used in context of sri lanka and tamil fishermen conflict. I think it has something to do with fishing.
